right rear battery box compartment). Always wear adequate ear protection, such as earplugs, when
operating this equipment as prolonged exposure to uncomfortable or loud noises can cause impairment
or loss of hearing. Do not wear radios or music headphones while operating the machinery.
Safe operation requires your full attention.
Do not operate the equipment while wearing sandals, tennis shoes, sneakers, shorts or
any type of loose fitting clothing. Long hair, loose clothing or jewelry may get tangled in
moving parts. Always wear long pants, safety glasses, ear protection and safety shoes when
operating this machine.
Always wear safety goggles or safety glasses with side shields when operating the mower.
Always be aware of what is behind the machine before backing up. Do not mow in reverse
unless absolutely necessary.
Always look down and behind before and while backing up.
When moving in reverse, depress slowly the throttle lever and avoid sudden
movement. Rapid movement of the throttle lever in either direction
could result in a reaction of the machine that can cause serious injury.
Never operate a poorly maintained machine.
Never attempt high speed maneuvering, especially in crowded, congested areas or on slopes.
Never allow persons to operate this machine without proper instruction or allow children to
operate machine. Allow only responsible adults who have read and understand
these instructions to operate this machine.
Never put hands or feet under any part of the machine while it is running.
Never carry passengers.
Never direct discharged material toward anyone. Avoid discharging material against
a wall or obstruction. Material may ricochet back toward the operator. Always disengage
the blades and wait for them to stop before crossing gravel drives, walks or roads.
Always keep clear of the mower blades and attachments during their operation.
Turn off blades when not mowing. Slow down before turning.
Turn the key to the OFF position, remove key and disconnect battery cables by pulling disconnect battery
cables by pulling LARGE RED exterior battery quick disconnect handle upward to remove & disconnect
all power to unit( located outer right rear battery box compartment) before removing the grass catcher or
unclogging the discharge chute. Never clear the discharge chute with the machine running. Turn
the key to the OFF position, remove key, and make sure the blades have stopped before cleaning.
Use a stick to clear a plugged discharge area. Never use your hand!
Do not operate the machine while under the influence of alcohol or drugs.
Exercise caution when loading or unloading the machine onto a trailer or truck.
Data indicates that operators, age 60 years and above, are involved in a large percentage
of mower-related injuries. These operators should evaluate their ability to
operate the mower safely enough to protect themselves and others from serious injury.
If any attachment or additional weight is mounted on the rear or side of the unit (depending on
model), any rapid movement in either direction could result in a reaction of the machine
that can cause serious injury.
Clean flammable material from machine. Prevent fires by keeping battery compartment, deck and
operator’s station clean of accumulated trash, grass clippings, and other debris.
Using a ramp
Use extreme caution when loading and unloading a unit onto a truck or trailer with a ramp.
Use only a single, full width ramp; do not use individual ramps for each side of the unit.
Having a full width ramp provides a surface for the mower frame to contact if the
unit starts to tip backwards. It also reduces the risk of a wheel going off and the
machine tipping over. Do not exceed a 20 degree angle between the ramp and the ground
or between the ramp and the trailer or truck. When on a ramp avoid sudden acceleration.
Slope operation
Slopes are a major factor in loss-of-control and tip-over
accidents, which can result in severe injury or death. All
slopes require extra caution.
REMINDER: It is recommended to only operate on slopes of 20 degrees or less.
Use extreme caution when operating on slopes.
• Be extremely careful changing directions on a slope.
• Slow down.
• Do not operate where the machine could slip or tip.
• Turn slowly
• Turn on the most level part of the slope

10
• To maximize traction, it is better to turn the front of the machine uphill, rather than downhill. If drive
tires lose traction, steering control is lost which could cause serious injury or death.
• If it becomes necessary to turn downhill, turn slowly and gradually.
Do not remove or modify the stabilizer wheels. Watch for holes, ruts, bumps, rocks or other hidden
objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles.
Remove obstacles such as rocks, tree limbs, etc. Keep all movement on slopes slow and gradual. Do not
make sudden changes in speed or direction. Avoid starting and stopping on a slope. If tires lose traction,
disengage the blades and proceed slowly straight down the slope.
Mow a safe distance (minimum of 10 feet, 3.05 meters) away from drop-offs, retaining walls, drainage
ditches, embankments, water, and other types of hazards to avoid a wheel dropping over the edge or to
avoid the ground from breaking away. This will reduce the risk of the machine suddenly rolling over
causing serious injury or death. Do not mow on wet grass. Reduced traction could cause
sliding and loss of steering control. Do not tow on slopes. The weight of the towed equipment
may cause loss of traction and control. Do not try to stabilize the machine by putting your foot
on the ground. If the mower’s tires lose traction when operating on slopes, disengage the deck blade switch,
release Throttle Lever, & Operator Presence Safety Lever & turn the key to the
OFF position and get help OR in EMERGENCY release Operator Presence Safety Switch
to engage brakes & stop the blades. Never make sudden starts, stops, turns, or reverse direction,
especially when maneuvering on slopes. The steering is designed for sensitive response. Rapid movement
of the steering control levers in either direction could result in a reaction of the machine that can cause
serious injury. Never stop suddenly while backing down slopes. This action may result in a reaction of the
machine that can cause serious physical injury. The Mean Green Mower is capable of operating
horizontally (traverse) on moderate slopes. When operating on slopes up to 20 degrees, be aware of any
conditions that may cause the mower drive tires to lose traction resulting in a possible loss of control of the
machine. An operator should not operate on a slope until he is thoroughly familiar with the equipment. It is
strongly recommended that the operator drive the machine off of the slope, using extreme caution, if any
sign of loss of traction is detected. Wait until the condition that caused the problem is resolved before
attempting to operate on the slope again. Terrain conditions can affect traction resulting in possible loss of
control of the machine. Some of the conditions to be aware of are:
1. Wet terrain
2. Depressions in the ground; i.e. holes, ruts, washouts
3. Mounds of dirt
4. Soil type; i.e. sand, loose dirt, gravel, clay
5. Grass type, density, and height
6. Extremely dry conditions of grass
7. Tire pressure
The attachments mounted to the mower will also affect the way it handles on a slope. Be aware that each
attachment’s characteristics vary. Another consideration is to always mow a safe distance
(minimum of 10 feet 3.05 meters) away from drop-offs, retaining walls, drainage ditches, embankments,
water, and other types of hazards to avoid a wheel dropping over the edge or to avoid the ground from
breaking away and always be aware of what is located at the bottom of the slope. This will reduce the risk
of the machine suddenly rolling over causing serious injury or death. Extreme caution should be used when
there is a hazard located at the bottom of the slope. Some examples are:
1. Water; i.e. lake, river
2. Cliffs, retaining walls
3. Roads, highways
4. Buildings
5. Rocks
These are just a few examples of situations when caution must be used when operating on a slope. There
are many other possibilities too numerous to mention. Just remember to always exercise extreme
caution when operating on any slope.
Children
Tragic accidents can occur if the operator is not alert to the presence of children.
Children are often attracted to the machine and the mowing activity. Never assume that
children will remain where you last saw them.
Never leave machine unattended with key in switch, especially with children present.
Children or bystanders may be injured if they move or attempt to operate the machine while it is
unattended. Always disengage deck blade switch & turn key to OFF position and
remove key. Keep children out of the mowing area and under the watchful care of
a responsible adult other than the operator. Be alert and turn the machine off if children enter the area.
Before and while backing, look behind and down for small children.
Never carry children, even with the blades off. They may fall off and be seriously

11
injured or interfere with safe machine operation. Children who have been given rides
in the past may suddenly appear in the mowing area for another ride and be run over
or backed over by the machine. Never allow children to operate the machine.
Use care when approaching blind corners, shrubs, trees, the end of a fence or
other objects that may obscure vision. Never allow children or others in or on towed equipment.
Operator Controls
Steering Control: Fingertip drive control levers provide independent speed control, braking and
neutral to each drive wheel for moving forward or reverse, stopping, and power turning.
Fig.J
Note: For smooth operation of this machine, avoid quick, jerky movements of the drive levers. Move the
drive levers smoothly and deliberately.
Operator Presence Safety Levers (OPS)(Fig.J)
Located on the upper handle assembly directly above the handle grips.
When these levers are depressed, the OPS system senses that the operator is in the normal operator’s
position. When the levers are released, the OPS system senses that the operator has moved from the
normal operating position and the mower will automatically stop, electric brakes are automatically applied,
and mower blades will stop in less than 3 seconds.
Drive Levers (Fig.J)
Located on each side of the upper handle assembly ahead of and below the handle grips.
These levers individually control the speed and direction of each drive wheel. When the speed control
lever is moved out of the neutral position and the neutral lock latches are moved into the drive position, and
the drive levers are released, the drive wheels are engaged in the forward direction. Squeezing the left hand
and/or right hand lever causes the left hand and/or right hand drive wheel respectively to slow down, stop,
or reverse, depending on how far each drive lever is “squeezed”. Squeezing the drive levers beyond the
neutral position causes the drive wheels to engage in the reverse direction regardless of the position of the
neutral lock latches and the speed control lever.
Neutral Lock Latches (Fig.J)
Located on the upper handle assembly on the ends of the handle grips.
These latches allow the operator to lock the drive levers in a “neutral” position where the drive wheels
are not engaged in either a forward or reverse direction.
Operation
Starting Mower: 1. Depress Operator Presence Safety Levers 2. Turn Master Power Key to “On”
Driving the Mower
Drive Lever/Neutral Lock Latch Operation
To lock the drive levers in “neutral lock”, squeeze the drive levers to the “neutral” position (Do Not
squeeze the drive levers all the way back as this will cause the drive wheels to go into full reverse
direction). Place thumbs on the inner lobe of the neutral lock latches and rotate them under the drive levers
into the “neutral lock” position. Release the drive levers.
If the neutral lock latches are not completely engaged the drive levers could
unexpectedly slip into the forward drive position. If the drive levers slip into the drive
position the unit could lurch forward and cause injury or property damage.
Be sure the drive levers are past the detent and securely seated at the bottom of the neutral
lock latches.

Safety Start Interlock System
The machine is equipped with a safety start interlock system
consisting of the Operator Presence Safety Lever and Deck Blade Switch.
IMPORTANT:
Blade Warning Light System: Fig.6A (located on top of mower in front of battery
compartment)
A 3 light system to assist operator with optimal mowing performance in all grass conditions
showing speed and performance of each blade. NOTE: Allow 10 seconds for the blade lights to
turn on after blades are engaged. (Operator can start mowing grass before lights are on.) The
lights run in order of the blades –for example, the left light is monitoring the left blade, center
light is monitoring center blade and right light is monitoring right blade. Once lights are on,
operator should see solid GREEN. This will indicate the blades are running at full speed and
optimal power.
GREEN Light: Operator can maintain speed and the cutting height is accurate for optimal
performance.
As the operator enters thicker grass, a light or lights (depending on which blade is cutting the
thickest grass) will be YELLOW. If this occurs, it is best to slow speed and allow blades to return
to GREEN. If slowing speed does not return lights to GREEN, operator may need to slightly raise
the deck to return to GREEN and an optimal cutting performance. A ¼ inch rise in the deck can
make a huge difference in cut quality and cutting speed especially in tall, wet grass.
YELLOW Light: Reduce speed. Operator may need to raise the deck ¼ inch to keep the deck at
optimal power and blade performance.
3C

15
If the operator continues to run the mower in YELLOW with longer, taller, wet grass, the lights
will turn RED. RED lights indicate the blade tip speed and power is at the lowest point and is on
the verge of shutting down. Continuing to run in RED will result in your blade or blades shutting
down completely, requiring the operator to turn Deck Blades Off and then On to reset the PTO.
TO AVOID THE BLADES SHUTTING OFF- SLOW DOWN AND RAISE DECK SLIGHTLY!
This means the grass is too tall, thick or wet and may need recut in this area for optimal
performance.
RED Light: Slow speed. Raise deck. You may need to look at double cutting area if grass is too
tall or thick.
NOTE: Once the blade/blades have shut down, the red light will go to a blinking green light. This
will inform the operator that a blade/blades have shut off and will need reset by turning Deck
Blades Switch Off and then On. Operator will also see flashing GREEN lights when turning the
mower deck blades off letting operator know that all blades have shut down.
Fig.6A
Operating suggestions
DANGER: Prior to operating the mower the operator should be thoroughly familiar with the proper
use and operation of the equipment, should read the manual completely and thoroughly, and should have
attempted slow moving maneuvers to become familiar with the operation of the equipment before
attempting normal speed operation. An inexperienced operator should not mow on slopes or on uneven
terrain and should always mow in Low Mode/Slow Drive Speed.
WARNING: Sharp depressions or raised obstacles (such as gutters or curbs) should not be directly
approached at high speed in an attempt to “jump” them as the operator could be thrown away from the
equipment. Approach at a slow speed and angle one drive wheel at the obstruction. Continue at an angle
until the wheel clears and then pivot the opposite wheel around. When turning on soft wet turf, keep both
wheels rolling either forward or backward. Pivoting on one stopped wheel can damage turf. This is
especially important when mowing. Keep blades sharp. Many professional mowing companies
have additional sets of blades and change blades twice a day: once in the morning and again at noon. Many
problems with incorrect cutting patterns are due to dull blades or blades which have been sharpened
incorrectly. Information on sharpening blades is listed in this manual’s maintenance section.
In addition, most communities have individuals or companies which specialize in sharpening mower
blades. Blade sharpness should be checked daily.
DANGER: Never work with blades while key is in the ignition switch. Always place deck blade
switch in the disengaged position, release Throttle Lever & Operator Presence Safety

when handling blades. Always check for blade damage if mower strikes a rock, a branch or another
foreign object during mowing!
Direct grass discharge to right (with side discharge models),
away from un-mown area. Select a mowing pattern that directs grass discharge
towards the outside, not towards center, of mowing area. Generally, this
means using a pattern utilizing left turns because side discharge
is to right. In any case, avoid throwing grass discharge onto
un-mowed area because grass is then mowed “twice”. Mowing
twice puts an unnecessary load on the unit and reduces mowing efficiency.
When mowing a lawn for the first time cut grass slightly
longer than normal to avoid scalping uneven terrain. When
possible, it is best to use the cutting height that was used in the
past. When cutting grass taller than six inches, you may want to
mow the lawn twice to achieve a better quality of cut. During normal mowing cut only about 1/3 of the
grass blade. Cutting more than that is not recommended unless grass is sparse or it is the end of the
mowing season. Alternate mowing direction to keep the grass growing straight and better dispersion of
the clippings. Remember, grass grows at different rates at different times of the year. Mow more often in
the early spring to maintain the same cutting height. As the growth rate slows in mid-summer,
mow less frequently. If you cannot mow at a regular interval, mow at a high cutting height; then mow again
two days later at a lower cutting height. Raise the cutting height of the mower if the cutting width of
the mower is wider than the previous mower. This ensures that uneven turf is not cut too short.
Raise the cutting height of the mower if the grass if slightly taller than normal or if it contains a high
degree of moisture. Then mow it again with the cutting height set lower.
WARNING: Never direct discharge of material from
mower deck towards bystanders. Do not operate the
mower without the discharge chute (with side discharge models).

Clean battery compartment, drive motor compartment, mower deck, seat etc. of all dirt and debris. DO
NOT spray electronics/battery compartment with water. Do not use, solvents, hard cleaners or
abrasives. Use only compressed air. Always wear adequate eye protection when servicing the
batteries, or when grinding mower blades and removing accumulated debris.
Never attempt to make any adjustments or repairs to the mower’s drive system, mower deck or any
attachment while the traction drive system is running or deck blades are
engaged. Repairs or maintenance requiring power should be performed by trained maintenance personnel
only. Never work under the machine or attachment unless it is safely supported with jack stands. Make
certain machine is secure when it is raised and placed on the jack stands.

17
The jack stands should not allow the machine to move
when the traction drive system is running and the drive
wheels are rotating. Use only certified jack stands. Use only appropriate jack stands, with a minimum
weight rating of 2000 pounds (907.2 kg) to block the unit up. Use in pairs only. Follow the instructions
supplied with the vehicle stands. Do not touch hot parts of machine.
Keep nuts and bolts tight, especially the blade attachment bolts. Keep equipment in good working
condition. Never tamper with safety devices. Check their proper operation regularly. Turn the key to the
OFF position before unclogging the discharge chute. Never clear the discharge chute with the machine
running. Turn the key to the OFF position and be sure the blades have stopped. Disconnect battery cables
by pulling disconnect battery cables by pulling LARGE RED exterior battery quick disconnect handle

Keep unit free of grass clippings, leaves and other debris. Wear adequate eye and hearing protection when
cleaning the unit. Always wear safety glasses and protective gear near battery. Use insulated tools.
Regular Maintenance
Regular maintenance is the best prevention for costly
downtime or expensive, premature repair. The following pages
contain suggested maintenance information and schedules
which the operator should follow on a routine basis. For more
detailed information order the correct parts manual for your unit.
Remain alert for unusual noises, they could be signaling a
problem. Visually inspect the machine for any abnormal wear or
damage. A good time to detect potential problems is while
performing scheduled maintenance service. Correcting the
problem as quickly as possible is the best insurance.
Daily inspect mower for grass clippings and wire and string
tangles. The underside of the mower deck may collect a buildup
of grass clippings and dirt, especially when grass is wet or
has high moisture content. This build-up will harden, restricting
blade and air movement and will probably show a poorer quality
of cutting. Therefore it should be removed routinely.
To do this it will be necessary to raise and block the deck,
using jack stands or blocks, in the full up position and scrape the
build-up from underneath.
Some repairs require the assistance of a trained service
mechanic and should not be attempted by unskilled personnel.
Consult Mean Green Products when assistance is needed.
Torque Values: WARNING: Particular attention must be given to
tightening the drive wheel lug nuts and blade spindle
bolts. Failure to correctly torque these items may
result in the loss of a wheel or blade, which can cause
serious damage or personal injury. Call your Mean Green Products Dealer for assistance.
Torque values are given below:

Lug nuts only - It is recommended that these be checked after
the first 2 hours of operation, initially, every 100 hours and
following removal for repair or replacement.
Tires (Every 40 hours)
It is important for level mowing that the rear tires have the same
amount of air pressure. The recommended pressures are: 12 - 14 psi in rear tires.
Front tires are either no flat tires (do not require air) OR pneumatic tires with the
recommended pressures of 12-14 psi.
Lubrication
Use SAE multi-purpose grease for front wheel bearings.
IMPORTANT: Recommended maintenance at the beginning of each mowing season and every
50 hours of operation.
Electrical system
This mower operates on a 48 volt electrical system.
Refer to the Electrical section of this manual for detailed
information.
Mower blade maintenance
Check the mower blades daily, they are the key to power
efficiency and well-groomed turf. Keep them sharp, a dull blade
will tear rather than cut the grass, leaving a brown ragged top on
the grass within a few hours. A dull blade also requires more
power. Replace any blade which is bent, cracked or broken.
WARNING: Never attempt to straighten a bent blade by heating, or
weld a cracked or broken blade as the blade may break and cause serious
injury. Replace worn or damaged blades.
DANGER: Never work with blades while key is in
the ignition switch. Turn key to OFF position,
remove key from switch and disconnect battery cables by pulling disconnect battery cables by pulling
LARGE RED exterior battery quick disconnect handle upward to remove & disconnect all power to unit
(located outer right rear battery box compartment).
Block up mower when you must work under it. Wear gloves when handling blades. Always check for blade
damage if mower strikes a rock, branch or other foreign objects during mowing!
WARNING: Always wear adequate eye protection when grinding mower blades.
Mower blade removal
Use a 9/16” wrench or socket to remove the 3/8” cap screw
holding the blade to the motor shaft from underneath. It may be
necessary to use a 1-1/4” channel lock pliers to keep the blade adapter from
turning while removing blade cap screw. NOTE: The blade adapter will come off when the blade cap
screw is removed. Touch-up sharpening can be done with a file. Check the blades for balance following
grinding. A commercial balancing tool is available through most hardware
supply stores, or balancing can be done by placing the blade on an inverted line punch or 1/2” bolt. Blade
should not lean or tilt. Spin the blade slowly, blade should not wobble. If blade is out
of balance, true it up before reinstalling. Lay the blade on a flat surface and check for distortion. Replace
any distorted blade.
Mower blade installation
Do not re-use spindle bolts which have stripped, worn or undercut threads. Make sure that the blade adapter
is seated properly on the blade motor shaft before tightening the blade cap screw. Use a 9/16”
socket with a torque wrench to re-attach the blade to the motor shaft from underneath. It will be necessary
to use a 1-1/4” channel lock pliers to keep the blade adapter from turning. Torque cap
screws on motor shafts to 60 foot-pounds (67.8 Nm) when reinstalling blades.
IMPORTANT: The blade sail (curved part) must be pointing upward toward the inside of the deck to
ensure proper cutting.
IMPORTANT: When mounting blades, rotate them after installation to ensure blade tips do not touch each
other or sides of the mower.
WARNING: Failure to correctly torque the bolt may result in the loss of the blade which can cause
serious injury.
